Ideally I'd like a sectioned 593 on display, as there's not a lot to see on the outside of a turbojet engine except the ancilliaries - and you can see those by opening the engine bay doors.
There used to be one of those hanging from the Foyer roof of the Engineering Department of Leeds University. AFAIR is was motorised and the HP & LP Spools used to rotate at a fraction of an RPM. I think there were internal lights too and/or the spools were painted as well. I think it was also in a Concorde type nacelle. This must have been in the 70's as I used to go to the annual Open Days with my Grandad who worked there.
I can't seem to find any reference to it as to whether it is still there, disposed of or in storeage ??? Perhaps someone has contacts ???
regards
Howie
